Will stopping immigration cause labor shortages?

Whether halting immigration causes labor shortages depends heavily on a country's demographics, economic structure, and which sectors are most reliant on immigrant labor. Let me pull in some current context to give you a grounded answer.## Short answer: In many cases, yes — especially in specific sectors and regions, though the broader economy-wide effect depends on context.

Real-world evidence from the U.S. in 2025–2026 gives a fairly clear picture of what happens when immigration is sharply curtailed:

Sector-specific shortages are already showing up. Job growth in industries heavily reliant on immigrant labor — hotels, restaurants, construction, and health care — has been weaker than the rest of the private sector since the start of 2025. Agriculture is a prime example: the farming industry, where a large share of laborers are foreign-born, could suffer as immigration enforcement continues, and the Labor Department itself warned that these policies risk creating a labor shortage in that sector. The Federal Reserve has independently confirmed this pattern: the Fed's Beige Book from October 2025 identified labor supply tensions in agriculture, construction, hospitality and manufacturing tied to migration policy changes, including hiring difficulties, project delays, and regional wage pressures.

U.S.-born workers generally haven't filled the gap. This is the key empirical finding that challenges the "immigrants are taking jobs from natives" theory. The unemployment rate for U.S.-born workers actually increased from 4.3% in January 2025 to 4.7% in January 2026, even as the number of foreign-born workers dropped. In fact, U.S. workers did not reenter the labor market as foreign-born workers fell — labor force participation for U.S.-born individuals actually declined slightly over that period. A National Immigration Forum analysis summarizes the mismatch: employers across many sectors are calling for more workers than the domestic labor pool can currently provide, suggesting that reductions in the foreign-born workforce are not being offset by higher employment among U.S.-born workers, leaving persistent gaps in critical occupations.

Macro-level effects are mounting too. Noncitizen workers comprise roughly one-fifth of the U.S. labor force, so a sustained outflow has ripple effects. Models project a net reduction in the labor force of around 4 million workers by 2028 and 11 million by 2035 under current trends, and the Congressional Budget Office projected in September that hundreds of thousands of removals between 2026–2029 may create a labor shortage and drive up inflation. Economic growth projections have already been revised downward as a result: one study projects average annual growth falling to 1.3% from 1.8% between fiscal 2025 and fiscal 2035 due to these policies.

But it's not uniform or instant. It's worth noting that the effect isn't a sudden, economy-wide crisis — it's concentrated. Some estimates attribute 40–60% of the 2025 slowdown in non-farm job creation to reduced immigration, though weaker overall labor demand also played a role — while there was no widespread labor shortage or major overall wage impact, effects were already visible in specific sectors and regions with higher shares of foreign labor.

Why this happens (the underlying mechanics)

The counter-argument

Proponents of restriction argue the opposite can happen in theory — tighter labor supply should force wages up and pull more native workers (including those currently out of the labor force) back in. That's the stated rationale behind some U.S. policy: some officials, including Vice President JD Vance, have argued that limiting immigration will raise wages and create more job opportunities for U.S.-born workers, and the administration has contended workers are available to counter labor shortages. So far, the 2025–2026 U.S. data hasn't borne this out at scale, but it remains the core theoretical case for restrictionists, and outcomes could differ in economies with more labor slack or different demographics.

Bottom line: Based on current evidence, stopping or sharply reducing immigration tends to create real, measurable labor shortages in specific sectors (agriculture, construction, hospitality, health care, manufacturing) and can slow overall economic growth — without reliably being offset by native-born workers filling those jobs, at least in the short-to-medium term. Whether this constitutes an economy-wide "shortage" depends on the country's demographic trajectory and how concentrated the affected industries are.
